ABC's Martha Raddatz now on the developing information about the suspects international connections and what we're learning at this hour and -- We believe that these two men reported to be Brothers. Are in fact from overseas as George mentioned possibly from Chechnya. Tell us what we know with this point what we've been able to confirm.

People talking about a domestic attack felt like it would be -- -- this would be yet these guys proved their point but the international thing really really raises the red flag. On whether someone else is out there and whether more attacks -- plant.
